Chi: internal energy, the essence of life. It moves inside of us. It flows through our bodies. Gives us power from within.

MR. HAN, The Karate Kid (2010)

All energy is only borrowed and one day you have to give it back.

JAKE SULLY, Avatar (2009)

Kid, I've flown from one side of this galaxy to the other and I've seen a lot of strange stuff. But I've never seen anything to make me believe that there's one all-powerful Force controlling everything. 'Cause no mystical energy field controls my destiny. It's all a lot of simple tricks and nonsense.
